Abstract

Dysmenorrhea is common in Japanese women. In our study, about half used self-medication, while some preferred complementary/alternative medicine. Dysmenorrhea is significantly associated with younger age and employment status.

Characteristics and Determinants of Primary Dysmenorrhea in Young Adults

“…Other studies reported that adopting weight management programs also caused an increase in menstrual pain (Montero et al, 1996). However, in contrary our study did not find an association between BMI and SFT to the occurrence of dysmenorrhea, studies reported by Ohde et al (2008) supported our findings (Ohde et al, 2008).…”

“…Although the effect seen between family size and dysmenorrhea was mild, it was surprising that females from small families were more inflicted than those from large families; the reason for such an observation is difficult to explain. Studies from different regions covering a large number of adolescent population reported socioeconomic status and literacy to have a positive correlation with dysmenorrheal (Klein and Litt, 1988;Patel et al, 2006), contrary to this, Ohde et al (2008) reported no association to income or education with dysmenorrheal.…”

Epidemiology of Dysmenorrhea among University Students in Egypt

“…However, it should be taken into consideration that the age of the university students ranged from 18 to 23 years, and this tight range might explain why the impact of age was not detected in the current study. Other reports concluded that dysmenorrhea peaks in late adolescence, then the incidence falls with increasing age [11,24,25,27]. Also, early menarche was not associated with occurrence of dysmenorrhea which consisted with previous studies [11,28], but did not agree with others [15,16].…”

“…Worldwide, the prevalence of dysmenorrhea varied widely according to the age of the study group, the length of recall/follow-up, and definition of pain whether any pain or pain interrupting with daily activities. In Japan, a prevalence of only 15% was detected in a one-month prospective study over 823 women (18-51 years) [24], while in a study on Chinese women (20-34 years), the 12 months follow-up ported severe pain (8)(9)(10). Forty nine percent reported moderate score of pain (4-7) and the rest of (23%) students had mild pain.…”

The magnitude, long-term trend and lifestyle risk factors of dysmenorrhea and premenstrual syndrome

“…A total of 14 individual studies [3,4,11,[64][65][66][67][68][69][70][71][72][73][74] and two systematic reviews [10,45] presented data on the prevalence and/or incidence rates of dysmenorrhea.…”
